Product description

The OTTO Fugenfux® set consists of four dimensionally stable tools made of high-quality plastic, specially developed for professional joint smoothing. The different radii enable optimum adaptation to different joint widths. The material is chemical-resistant, slightly flexible and ensures even surfaces without sticking. Thanks to the ergonomic shape each tool sits securely in the hand and enables precise working – even in hard-to-reach places.

Typical areas of use are construction, sanitary installation, tiling work, interior fit-out and renovation. For best results it is recommended to remove excess material beforehand and draw off the joint evenly with the matching radius.
